Migrating EKS Applications Between AWS Outposts, AWS Regions, and On-Premises

To migrate an EKS application between AWS Outposts, AWS regions, and on-premises, perform an out-of-place recovery of your EKS application.

When you restore an application, the persistent volumes, secrets, and configuration maps are also restored.

Before You Begin

If a passkey has been configured for restores, obtain the passkey so that you can enter it when prompted during the browse or restore operation.

Procedure

1. From the navigation pane, go to Protect > Kubernetes.

   The Applications tab appears.

2. On the Application groups tab, in the row for the application group that you want to restore, click the action button , and then click Restore.

   The Select restore type page appears.

3. Click Full application.

   The Restore page appears.

4. Select the applications to restore.

5. To select a specific backup copy to restore from, do the following:

   By default, Commvault restores content from the first available, valid backup copy that it finds.

   1. In the upper-right corner of the page, click Settings.

      The Settings dialog box appears.

   2. From the MediaAgent list, select the access node that contains the backup copy.

   3. From the Source list, select the backup copy.

   4. Click Save.

6. Click Restore.

   The Restore options dialog box appears.

7. For Type, select Out of place.

8. For Destination cluster, select the cluster to restore the content to.

   You can select any Kubernetes cluster that is added to Commvault.

9. From the Access node list, select the access node to perform the restore.

   For optimal performance, select an access node that has low latency to the Kubernetes cluster and the backup copy.

10. In the Application name box, enter a name for the restored application.

11. Specify the namespace to restore the application to:

    • To select an existing namespace, from the Namespace list, select the namespace.

    • To create a namespace, move the Enter namespace manually toggle key to the right, and then enter a name for the namespace.

12. From the Storage class list, select the StorageClass to provision PersistentVolumes from.

    If you intend to back up the restored application with Commvault, select a StorageClass that has a CSI provisioner, an attacher, and a snapshotter.

13. To delete and overwrite existing data, move the Unconditionally overwrite if it already exists toggle key to the right, and then click Yes in the confirmation dialog box.

    If any data matching the restore data exists in the destination, Commvault deletes the existing data before starting the restore process.

14. Click Submit.
